This invention pertains to laundry drum construction. 3

I The ordinary commercial laundry drum is of cylindrical shape andcomposed of wooden 5 parts which are alternatively soaked and dried.Consequently such parts are subjected to expansion and contraction whichloosens the several joints between the parts. Therefore, it is one oftheobjects of this invention to provide a construction which willprovide a secure fastening for the various parts and one which may betaken up to prevent looseness. 7

Another object is to provide a structure which will securely hold theribs in place and in their proper relation with the end faces.

Another object-is to provide an adjustable bracing structure which issimple and economical to construct and easy to install.

' lowing description, taken in connection with the accompanying drawing,in which Figure 1 is an end view of a laundry drum embodying thisinvention; j

Figure 2 is a partial section somewhat enlarged, taken on line 2 2 ofFigure 1; and

Figure 3 is a detail section showing the construction of the braces.

The laundry drum shown in the drawing is constructed of a series ofslats 1, which run lengthwise of the drum, and are-shown only 'in endview in Figure 1. These are secured in any suitable manner to the rim ofan end face 2 and are ordinarily held in place by a band or'hoop 3. Theslats and theend face 2 are usually constructed of wood. The end facemay be constructed ofa series of transverse boards which may be spacedfrom each other,

as illustrated in Figurel, so as to provide'for spaced plate 5 of castiron,steel, or other-suitable j material. j 'This face is usuallyprovided with *a'suitable trunnion-on which thedrum may rot-ateand'maybeprovided with acoupl'ing member 6 p for driving the drum. ,Theface plate 5' may be bolted to'the end face by bolts Jorother suitablefastening; Arrangedjaround the periphery "of the end 'face'andradially'outsidegofthe face plate o is a series of braces'8. -Thesewbra'cesai e provided with suitable bolt holes 9, which may beelongated to provide for adju'stnient, "and through which bolts 10'maybepassed for securing the braces to. the"end face2. "The braces 8 arearcua-te in form and are provided with terminalabutme'nts ll'ada-ptedteen- 'g'age the protruding end of the rib 4. Each brace 8 bridges'theinterval between adjacent ribs'and bears against thoseribs at'its'end's.

Further objects will appear from the fol- :The abutments 11, which bearagainst the ribs, are slotted radially so, as to provide sockets 14, forthe legs of a U-bolt 12 which provides a tension'member forclamping'tlie races againstthe sidesof the ribs.-' The closed end .ofthe U-bolt is hooked overa lug 13 on the face plateb. There are anumendswith clamping nuts 15, bearing against 'collars 16 which rest uponthefoutside ofthe braces 8. It, will be seen that by' -drawing up onthe'nuts 15rthe braces Smay be drawn inwardly so'as to clamp the ribsLsecurely therebetween. The braces are tensioned to sockets 14: and areprovided I at their outer the face plate 5 so as to provide a rigiddriving structure.

It will be seen that this invention provides and one which is very rigidand in which the efiects of expansion and contractionmay be braces 8 maybe kept securely clamped against the ribs so that said ribs are alwayssecurely It is obvious that various changesmay be a very simpleconstruction for laundry drums compensated for by readjustment.
